Twenty year-old Mikiko Oguro (known as Kuromi to her co-workers) has just entered the dream job of a lifetime -- animation!

Naota Nanbada is a boring young boy who leads a boring life in a boring town. His older brother has left for America, and the closest he comes to any excitement is when his deadbeat dad has too much sake. But things change one day when a bizarre girl zooms up to him on a scooter and smacks him in the face with her guitar. What's more, once Naoto returns home he discovers that this strange woman has arrived ahead of him and moved in! Not only does she constantly engage in perverted activities with Naota's father and flirt with the young man himself, but she also claims to be an alien who is searching for the ‘Pirate King.' Now, Naota must learn to live with this new intruder, deal with an odd government agent who sports exceptionally large eyebrows and the mysterious Medical Mechanica, and come to terms with the fact that there are a variety of robots and weapons emerging out of his head - amongst other things. Perhaps boring wasn't so bad after all...
Though it may be that both FLCL and Jubei-chan are parodies of totally different genres, that's what they both still are. Glorious, hilarious, good-looking parodies. FLCL can be also some other things, but what it at least is is parody. If you've ever seen mecha-animes like, say, Neon Genesis Evangelion :P , you can see it is true. And Jubei-chan is of course a parody of samurai-series like, say, Kenshin - Reminicense.
Linn Suzuki made her way to Tokyo in search of her elder brother but found trouble instead. Lovely Detective Miho Kuon comes to Linn's aid as she is accosted by thugs, and thus begins their adventures together. Linn must endure geeky magicians, fierce tree spirits, and her 100-year-old master all while trying to stay clothed! Full of action and fanservice, Kotetsu is a debacle of martial arts mayhem.
The Adventures of Kotetsu and Jubei-Chan both share a slapstick element that ties into a very interesting take on Swordstyle martial arts. The former is a bit more "adult" than the later, but I'm positive that one would likely enjoy one as much as the other, so long as you weren't too young ^_^

There's never a dull day for Ranma as he attempts to find a cure for his curse, train to become stronger, and grapple with the fact that half of himself may be more feminine than his fiancée!
